Whether CEI and Consumer Alert had standing, including redressability, to challenge NHTSA's refusal to lower the model-year-1990 CAFE standard.
Holding
Yes. The petitioners had standing, and the court could grant effective relief by ordering retroactive reconsideration of the standard.
Reasoning
NHTSA's objections largely repeated standing arguments the court had already rejected in an earlier CEI case. The court therefore treated that precedent as controlling on injury, causation, and the petitioners' ability to represent consumers affected by the challenged standard.
NHTSA's new redressability argument rested on a decision permitting it to reject a late-filed petition to alter a CAFE standard after the relevant model year had begun. That rule did not limit the reviewing court's statutory authority under 15 U.S.C. § 2004(a) to grant appropriate relief for an unlawful agency action.
A remand directing NHTSA to reconsider its decision could remedy the asserted injury even after the model year began. The court distinguished an agency's discretion not to entertain a belated private petition from a court's power to require reconsideration after finding deficient agency reasoning.
